The way microbes breathe, called heterotrophic respiration, is influenced most heavily by one environmental factor: moisture. That influence and its parameters is the subject of a new paper by Zhifeng Yan, Vanessa Bailey, and other scientists at PNNL.
Soil organic carbon, or SOC, plays a vital role in the carbon cycle. According to a recent study published in Soil Biology and Biochemistry, the complexity of the carbon differs with the size of the pore that contains it, yet its decomposability is driven by its proximity to microorganisms, not it's chemistry.
"These reports can transform fields and influence organizational strategy in the public and private sector," said Teeguarden.
A new study predicts that warming temperatures will contribute to the release into the atmosphere of carbon that has long been locked up securely in the coldest reaches of our planet. Scientists from more than 30 institutions across the globe, including PNNL, collaborated on the study.
Spatial relationships matter in surprising ways. A paper in ISME Journal describes a photosynthetic microbial mat, cultivated in a controlled laboratory setting and used to evaluate spatial relationships between productivity and diversity.
About The Division
Scientists within the Biological Sciences Division perform biological systems science research and develop technologies focused on how cells, cell communities, and organisms sense and respond to their environment. Our vision is to measure, predict, design, and control multi-cellular biological systems and bio-inspired solutions for energy, environment, and health.
Our investigator-initiated and multi-institutional collaborative research, unique scientific instrumentation, and national program leadership translate the latest scientific discoveries into technologies that are beneficial to the nation.
Our research has applications to energy, environment, and human health missions of the U.S. Department of Energy (DOE), the National Institutes of Health (NIH), and other federal agencies.
